In this episode we discuss topics ranging from a chemical in vegetables that can destroy cancer stem cells, chewing gum to prevent signing a song over and over, the first report of germ line gene editing in human embryo, neuronal hyperactivity and neutral stem cells, and the discovery of a new pluripotent stem cell. The second half of the show comes live from The Next-Gen Stem Cell Conference in Saratoga NY, where we interview four scientists about their work and conference experience.

Could High Blood Sugar Be a Cause of Alzheimer’s Disease? – Scientists suspect one of the drivers that causes the complex brain changes that lead to Alzheimer’s disease is the accumulation of plaques of a faulty protein called beta-amyloid and that too much sugar in the blood can speed up the production of this protein.

Relaxed DNA May Contribute to Aging – Analysis from scientists suggests that loosely wrapped DNA underlies the accelerated physical decline of Werner syndrome and promotes aging in the rest of the population.

Bat-Winged Dinosaur Discovery Poses Flight Puzzle – This article describes the fossilized remains of a small, feathered dinosaur, unearthed in eastern China, that probably sported bat-like wing membranes and might have been able to glide or fly short distances.

Finding the Body Clock’s Molecular Reset Button – Researchers at McGill and Concordia universities in Montreal, report that the body’s clock is reset during the process known as phosphorylation, when a phosphate combines with a key protein in the brain.

Chew Gum to Get Rid of That Song in Your Head: Study – This article reveals that chewing gum could be the best way to get rid of the annoying songs that play in our heads which some call as earworms, according to a team of researchers at the University of Reading in the U.K.

Scientists Stumble Across Unknown Stem-Cell Type – According to this article, a newly discovered type of stem cell could help provide a model for early human development — and, eventually, allow human organs to be grown in large animals such as pigs or cows for research or therapeutic purposes.

New Clues into How Stem Cells Get Their Identity – This article explains how the acquisition of a new cell identity is achieved; cells respond to information from their surroundings, in turn activating a specific combination of proteins at certain places on the DNA, to turn on a genetic programme.
